Designating a unique note pad instance

z/OS MVS Programming: Sysplex Services Guide
SA23-1400-00

When deleting a note pad, consider using the ETODCREATED keyword to ensure that the intended instance of the note pad is deleted. Specify the 16 byte timestamp of when the note pad was created. When a note pad is created, XCF stores this timestamp in the answer area that was provided for the request (if any). The timestamp is also stored in the answer area in response to a query note pad request as well as a create connection request. For programs that might have competing threads concurrently creating and deleting a given note pad, the timestamp can be specified on the delete request to ensure that the intended instance of the note pad is deleted.

If ETODCREATED is not specified, or if the specified timestamp is zero, the currently defined instance of the note pad is deleted.
